Solution Overview

Problem

Existing coffee makers often result in flavor and aroma loss due to prolonged exposure of coffee beans to air, and residual coffee grounds from previous grinding sessions can contaminate new beans, making it difficult to efficiently change coffee types and maintain freshness.

Innovation Solution

A coffee making system with a connected coffee bean package that prevents exposure to air, uses coffee bean fragments for easier packaging and grinding, and includes a dosing mechanism to ensure precise coffee bean supply, allowing for easy switching between different coffee bean types without residual grounds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If coffee beans are stored in the coffee bean holder for a long time before grinding, then the coffee maker can be prepared for use in advance, but the flavor and aroma of the coffee beans are lost due to prolonged exposure to air

Engineering Contradiction:
Improvepreparation timeVSAvoidair exposure
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The coffee bean holder is divided into multiple compartments, each capable of holding different coffee beans. This segmentation allows the system to store multiple types of coffee beans separately, preventing cross-contamination and allowing each compartment to be optimized for its specific coffee type while reducing overall air exposure time for each batch.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary grinding by grinding coffee beans immediately before brewing rather than storing them for extended periods. The multiple compartments allow the system to prepare different coffee beans in advance and grind them on-demand, eliminating the need for prolonged storage while maintaining freshness.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If a complete pack of coffee beans is emptied into the coffee bean holder, then the coffee maker can operate continuously, but residual grounds from previous grinding runs contaminate new beans

Engineering Contradiction:
Improvecontinuous operationVSAvoidresidual grounds contamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The coffee bean holder is segmented into multiple compartments that can be independently filled and emptied. This allows the system to process one compartment at a time, completely emptying each compartment before moving to the next, thereby preventing residual grounds from previous grinding runs from contaminating new coffee beans while maintaining continuous operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system is designed to completely discard the contents of each compartment after grinding, ensuring that no residual grounds remain to contaminate the next batch. The multiple compartments allow for efficient discarding and resetting of each section independently, maintaining productivity while eliminating contamination.

Inventive Principle:
Principle #34Discarding and recovering

3Adaptability or versatility

If the coffee bean holder is filled with new coffee beans whose taste differs from the previous filling, then the coffee variety can be changed, but residual grounds from the previous filling mix with the new coffee beans

Engineering Contradiction:
Improvecoffee variety switchingVSAvoidflavor mixing
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The coffee bean holder is divided into multiple separate compartments that can be independently filled with different coffee bean varieties. When switching coffee types, the system can empty one compartment completely and fill it with a new variety without mixing with residual grounds from previous varieties, maintaining flavor purity while enabling versatile coffee selection.

Inventive Principle:
Principle #1Segmentation

4Productivity

If the coffee bean package is opened and closed multiple times, then coffee beans can be supplied for multiple brews, but the repeated opening and closing increases exposure to air

Engineering Contradiction:
Improvemultiple brewsVSAvoidair exposure
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The coffee bean package is divided into multiple compartments, each containing a specific amount of coffee beans for one or more brews. Each compartment can be sealed independently, allowing the system to open only the specific compartment needed for the current brew while keeping other compartments sealed and protected from air exposure.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system effectively preserves coffee freshness by minimizing air exposure and eliminating residual grounds, enabling convenient and efficient switching between coffee bean types, ensuring each brew maintains the desired flavor and aroma.
